Dinocrates meanwhile wrapping his cloak about him lay full length upon the deck near them, and turned his face in the direction of the lily-white tower with its crown of leaping flames. For a moment he did not speak, and the children were so impressed by the wild beauty of the scene that they too were silent. The vessel, as strange to their eyes as were the sailors who formed its crew, glided slowly and softly over the dark water on which lay a pathway of crimson light. To and fro moved the sailors, sometimes singing, sometimes laughing, sometimes shouting to one another as they went about their work, but paying no heed to their visitors. The flames from the lighthouse rising and falling revealed a coastline with a fringe of white houses, and on the sea other ships moving in various directions, their sails sometimes lighted up brightly in the red glow of the fire. Rachel, who had sunk into a sort of happy dream, started when at last their companion spoke. “Do you remember,” he began, “what Bucephalus, that famous horse, has already told you concerning his master, Alexander the Great? How that he set out to conquer the world? Bucephalus has, I know, related to you how his master took the city of Halicarnassus in Asia Minor and visited the tomb of Mausolus, built by the sorrowing Queen Artemisia. That, however, was only the beginning of his victories. “A little later, when all Asia Minor owned his sway, he turned his thoughts to Egypt and conquered _that_ country also. Sailing in his barge up the great river Nile which waters the land, he came at last to where it flows out into the sea—this very sea upon which you are now sailing. But he found no city there, such as by the light of that beacon fire you now behold. Only a few poor huts stood then at the mouth of the great river. ‘Here,’ thought Alexander, ‘is the place for a mighty port, and here a mighty town shall arise. But whom shall I employ to build such a city for me? Who is the greatest architect now living?’ Instantly my name was upon his lips. For, only a year before, he had seen the great new temple I had completed at Ephesus, in honour of Diana. “At once he sent for me, and straight from the building of that temple in Ephesus I came hither. Let me now show you, little maids, what I found where now that lighthouse and that city stand. Rise, and bow with closed eyes seven times in the direction of the shore.” Rachel and Diana needed no second invitation. They leapt to their feet and obeyed.
